Wiseco Racer Elite Piston Kit for Honda CRF250R 2010–2015.

The Wiseco Racer Elite piston kit is the manufacturer's flagship product, designed and built without compromise for riders who put engine performance and reliability above all else. The asymmetrical piston skirt gives the piston exactly the properties it needs on both the exhaust and intake sides throughout the various stages of combustion, resulting in a lightweight final product that delivers up to 2.9 horsepower gains simply by swapping the piston. Durability, on the other hand, has been boosted with features such as reinforcements around the piston pin and upgraded piston ring characteristics. The bevelled piston ring seals the piston more effectively, while the precision-machined ring groove lets just the right amount of lubrication into the cylinder. The Racer Elite piston also features an ArmorGlide coating that maintains the piston's properties throughout its entire service life, reduces friction and minimises the effects of temperature fluctuation.
